This
paper investigates the effective use of finite element methods to characterize
the behavior of an automobile tire. A 3D finite element model of standard size automotive
tire is developed to better understand the tire deformation under loading
conditions. A parametric study of inflation pressure, normal loading, camber
angle and slip angle was carried out to capture the influence of these
parameters. A parametric study of the combined case scenario of the effects of
the previously mentioned parameters is also performed. Using these results, an
empirical model will be developed that will demonstrate how the hoop strains
measured on the inner surface of the tire could be used to quantify desired
parameters such as camber, slip, and normal load. This model will comprise
equations relating strains to the contact area, slip, camber, and normal load.
